Polyanionic Cellulose (PAC) (Polyanionic Cellulose) is a kind of nonionic cellulose ether featured the properties of high purity, high DS, particularly high viscosity or low viscosity. These products are demi-natural polymer additive, thickening agent, filtrate reducer.

Polyanionic Cellulose (PAC) is high purity product; the water solution of this white powder is transparent and viscid. As water-soluble polymer, it dissolves immediately in cold/hot water and can be used as a thickening agent, rheology controller, bond, stabilizer, colloid protector, suspending agent, and filtrate reducer.

Polyanionic Cellulose (PAC) is a good drilling mud additive and also an important material for confecting well liquid, a high mud volume product that featured high acid-resistance and salt-resistance ability.Polyanionic Cellulose (PAC) is a good filtrate reducer with the capacity of increasing viscosity and anti-high temperature (150&#176;C) in the freshwater, seawater, or even saturated brine well-completion liquid.Polyanionic Cellulose (PAC) is suitable for confecting the completion fluid with these 3 kinds of water above.

Usage:Polyanionic Cellulose (PAC) -HV is for water-based drilling fluids, which can effectively reduces the filtration rate of many water-based oil and gas drilling fluids and may also be used to increase and stabilize viscosity to improve hole cleaning and suspension properties in a wide variety of fluid environment.

Polyanionic Cellulose (PAC) -LV is for use in solids-laden, water-based drilling fluids, which can effectively reduces the filtration rate of many water-based drilling fluids, without causing significant increases in viscosity or gel strength.
